Abstract
Column-supported embankments provide a practical and efficient solution for construction on soft soil due to the low cost and short construction times. In recent years, geosynthetics have been used in combination with column systems to support embankments. The load transfer mechanism in these systems is a combination of soil arching and membrane effect of the geosynthetics. In this paper, numerical method was used to improve the understanding of the long-term performance of geosynthetic-reinforced embankments supported on end-bearing piles. The distribution of skin friction, axial force distribution, settlements on the embankment and foundation soil surface, and vertical stresses on the pile head and foundation surface were studied. Finally, the results from the numerical studies were compared with the results from different analytical methods. Based on the numerical results obtained, modified arching coefficient is presented for end-bearing piles.
